The Indian Space Research Organization‘s Aditya-L1 solar observatory that launched on September 2, 2023, marked a historic moment, as this was the first Indian satellite mission aimed at directly studying the Sun and investigating space weather.
Nestled at Lagrange Point 1 (L1) — the area of equilibrium between the Sun and Earth’s gravitational forces — the spacecraft will embark on a unique orbit known as a “halo orbit” that requires precision maneuvers to maintain its course. Goonhilly, in collaboration with ESA’s ESTRACK network, will be at the forefront of aiding the mission, providing essential communication and tracking support from its early stages.
Goonhilly’s 32 meter antenna, the world’s first, commercial, deep space antenna, is also the first to be integrated into ESA’s global network of deep space ground stations. This partnership between Goonhilly and ESA cements the Earth Station’s indispensable role in the international space community, offering much-needed international communications capacity, as a commercial entity.
As the Aditya-L1 spacecraft journeys toward L1 and conducts solar observations, Goonhilly’s GHY-6 antenna, in tandem with ESA’s deep-space communication antennas, will track the mission’s progress. The antennas will play a pivotal role in precisely determining the spacecraft’s location during critical stages, facilitating seamless command transmissions, and receiving invaluable telemetry and scientific data. This data will then be relayed to ESA’s ESOC mission control center in Darmstadt, Germany, before reaching ISRO for in-depth analysis.
“Goonhilly’s ongoing collaboration with ESA exemplifies our unwavering commitment to assisting the advancement of space exploration. Following the huge success of the Chandrayaan-3 lunar landing, we have been working hand in hand with colleagues at ESA and ISRO for many months to prepare for the Aditya-L1 launch, and we’re ready to act as the key communications provider for this exciting mission.Goonhilly is proving the business model for cost-effective support of space exploration and we now have unrivaled experience as the only commercial provider of this class of service having supported lunar missions for NASA, ISRO and iSpace in recent months.” — Ian Jones, CEO, Goonhilly Earth Station
